Why do people insist on downvoting in these types of questions. That's really in poor taste, I think. If you don't like something, just leave it alone.

Hmm.. the price probably depends on the Apple store (e.g. for me prices show in Euros) Which price should we note?

This is a great app for any documents organizer and good PDF reader. It also can unzip the zip files, as it's not natively handled by iOS. I use it everyday. It used to sell $0.99, but now they increased price.

Brings multi-tasking to iOS 3 way before iOS 4 was born. It actually works even better than iOS 4, from my opinion, because it doesn't leave every app open (which can bring batter down quickly) but it does let you configure if you want to do that per app basis. In other words, you can configure which app you want to automatically leave in background.

A dictionary, to put it simply. It uses definitions from Wiktionary, which I find both more concise & more helpful than those of Dictionary.com, for instance. More importantly though, it's got a fast, lean & intuitive interface. No superfluous features, but I never find myself missing any functionality. It's a joy to use, unlike any other dictionary app I've tried.

Textie provides free messaging between iOS devices a la SMS. If Textie isn't installed on the recipient device, the service will route the message to SMS on many US mobiles, & to email in every other case. Replies are delivered to Textie on the original sending device with push notifications. The icing on the cake is the slick, minimal interface.

WhatsApp is already on this list, but not only does it not integrate with SMS or email, but I've always found it to have extremely variable latency, from a couple of seconds to two days. Textie's latency has never exceeded twenty seconds for me.

Aggregates notifications from various services including Twitter and Facebook; the killer features of this, for me, are its integration with Buzz, which has no built-in iOS notifications, and Growl, allowing me to send notifications from scripts running on my desktop and get them on my iPod Touch.

Post to your posterous.com microblog, especially useful for posting pictures and location on-the-go. Similar to twitter feeds, but a bit nicer to view photo galleries for your viewers. It can be set up to auto-publish to twitter, facebook, tumblr, etc.

Of course, if data limits/costs are of no concern, just use Safari for the most beautiful browsing experience on iOS — but Opera Mini is perfect for travelling abroad, to keep data roaming costs to a minimum, or when you’re stuck with a slow connection.

I feel like a bit of a dork for posting this but I find it quite useful and simple. It's just a list app. It keeps a repository of all entries you make so you can quickly add them back the next time you need it. Make a grocery list and check them off. The next time you won't have to type out items you've already used, just add them to a new list from the remembered items.

Car navigation with full offline maps for probably every country out there. TomTom is well known for their own car navigation GPS's, but this version for iphone can become very handy from times to times where you don't have one proper device.

Engadget had an article a couple weeks ago about it. TomTom sold data to the Dutch police force, who then used it to set up speed traps based on the speed and location data. TomTom said they were shocked that the police would do this. I'm not sure what else they expected them to use it for when they sold it to them. engadget.com/2011/04/27/…

Remote control in which you can see the screen with free subscriptions and desktop versions. iPhone app costs quite a bit, but it's the best remote control for iPhone I've seem, and probably the first too. Works over web or within same intranet wifi.
